x=7
Step-by-step explanation:
4 + 3x = 6x-8 + 3 - 12
4 + 3x = 6x-17
-3x - 3x
4 = 3x - 17
+17 + 17
21 = 3x
divide by 3 on both sides
7 = x
switch the side that x is on because teachers like that
x = 7

x=7
Step-by-step explanation:
1) subtract the variable on both sides
4=3x-8+3-12
2) get the variable by itself
-8+3=-5-12 = - 17
4=3x-17
+17 + 17
21=3x
3) divide the variable with the whole number
21/3=7
so ... x=7
